I reject your premise. I do not believe that the primary motivation here is to protect less technical users. However even were I to accept that, I would say the change is an unacceptable one thus they should either figure something else out or do nothing.

I think they know that they are going to lose some users.

If you are a fan of open source, maybe this will be a good thing. Maybe this will drive more people and money to open source projects directed at making a better mobile OS.
